Nice run! I've been waiting a while for someone to do something like this (I had this post confused with the co-op run, so I didn't look at it at first).
How come you don't use psi agility though? Were the other stats just too vital?
Invisibility and teleport, yes, absolutely. I could have taken psi AG on my backtracking to ops, but the time to take it alone would have lessened the impact on the time, I think. I've experimented with psi AG a little beforehand, and didn't find it to be so very much of a time saver. I'll probably take it IF I should ever redo this run, because it makes the jump from the rocket to that ladder possible without using the teleport trick.
